Big monitors are the easiest way to increase white-collar productivity, and anyone who makes at least $50,000 per year ought to have at least 1600×1200 screen resolution. A flat-panel display with this resolution currently costs less than $500. So, as long as the bigger display increases productivity by at least 0.5%, you’ll recover the investment in less than a year. (The typical corporate overhead doubles the company’s per-employee cost; always remember to use loaded cost, not take-home salary, in any productivity calculation.) Apple and Microsoft have both published reports that attempt to quantify the productivity gains from bigger monitors. Sadly, the studies don’t provide credible numbers because of various methodological weaknesses. My experience shows estimated productivity gains of 5-10% when users do knowledge work on a big monitor. This translates into about an 0.5-1% increase in overall productivity for a person who does screen-focused knowledge work 10% of the day. There’s no doubt that big screens are worth the money.
